Patented Sept. 27, 1932 UNITED STATES PATENT OFFICE EVA SPERLING, OF NEW YORK, N. Y., ASSIGNOR TO PITTSBURG UTILITIES, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK INSTANTANEOUS Application filed May 23,

My invent-ion relates to water heaters and refers more particularly to an electrically heated water heater that is attachable to a conventional faucet.

One object of my invention is to provide an instantaneous water heater that is simple of construction, cheap to manufacture and eas ily attached to any faucet.

Another object of my invention is to prcvide an instantaneous water heater with a strainer between the inlet and the heating chamber.

A further object of my invention is to provide an instantaneous water heater with a dc tachable faucet attachment carrying a strainer and a rubber washer for making a leak proof seal when attached to a conventional faucet.

A further object of my invention is to provide an instantaneous water heater with means for screwing to a conventional bibb and with set screws for holding the heater to a faucet.

I attain these objects by the means illustrated in the accompanying drawing, wherein like parts have similar numerals throughout the several views, in which Figure 1 is a section of the heater taken on lines 1-1 of Figure 3.

igure 2 is a partial section taken on lines 2-2 of Figure 3.

Figure 3 is a plan taken on lines 33 of Figure 1.

Figure 4 is a plan of the device.

The device is comprised of a body 1, formed to provide a heating chamber 2, said body preferably rounded at 3 and having a boss 1, provided with an angularly arranged hole 5, communicating with the heating chamber 2 and this boss also carries a screw 6, for holding down the cap 7.

In order to hold this cap 7, to prevent the water leaking, the bosses 8 and 9 are provided for carrying the holding screws 10 and 11.

The interior of the body 1, has two notches l2 and 13, for holding the notched ends 14- and 15, of the resistor support 16, preferably formed as illustrated in Figures 1 and 2 and carrying the screws 17 and 18, that hold the WATER HEATER 1932. Serial No. 612,935.

ends of the resistor coil 19, and the two conduit leads 20, have one end electrically attached to the said screws 17 and 18, and the other end attached to a conventional electric plug, not shown.

The cap 7, is threaded inside at 21, to fit a conventional faucet and the plug 22, and has a hole 28, providing a shoulder and means for holdin the strainer, screen or filter 24, and in the inside of this plug 22, the rubber washer 25, is fixed, said washer having a hole 26, for engaging with a conventional faucet, not shown.

In the event that it is not desirable to use the plug 22, the screws 27, 28 and 29 may be used to hold the device to a faucet, etc.

Having thus illustrated and described the preferred embodiment of my invention, I do not wish to limit myself to the exact construction or arrangement of parts shown, since it is evident that modifications may be made therein without departing from the spirit of the invention or scope of the claims.

I claim 1. In an instantaneous water heater, an electrical and heat resisting flanged cup provided with an angularly arranged outlet, a flanged cap fixed to said cup, said cup carrying a water heating element therein, said flanged cap carrying a water filter, and means for attaching said cap to a conventional faucet.

2. In an instantaneous water heater, the combination of a flanged cup shaped heating chamber provided with an angularly arranged outlet, said heating chamber having notches therein positioning an electric resistor, and a flanged cap detachably held to said chamber and a filter within said cap.

3. In an instantaneous water heater, the

combination of a flanged cup shaped heating chamber provided with an angularly arranged outlet, said heating chamber provided with inside oppositely arranged notches positioning an electric resistor therewithin and a flanged cap detachably held to said chamber holding said resistor support and carrying a filter, said cap having internal threads for attaching to a conventional faucet.

4:. In an instantaneous water heater, the

y 2 i i 1,879,956

combination of a flanged cup shaped heating chamber provided with an angularly arranged outlet, said heating chamber notched to provide a support for positioning an elec- 5 tric resistor therewithin and a flanged cap detachably held to said chamber holding said resistor support and a multiple of screws for holding said device to a faucet.

5. In an instantaneous water heater, the combination of a flanged cup shaped heating chamber provided with an angularly arranged outlet integral therewith, said heating chamber having inside notches positioning an insulated support, an electric resistor fixed to said support, a cap detachably held to said chamber holding said resistor support, said cap having internal threads, a threaded plug within said cap, a screen in the bottom of said plug and a rubber washer adjacent the top of said plug.
